DummyJSON

DummyJSON is a free fake REST API that returns placeholder JSON data. It lets frontend developers build and test interfaces before the real backend is ready.

Requests to its endpoints return sample records such as products, users, posts, comments and recipes. A custom endpoint returns the JSON body you define, and a server package lets you run mock data locally. Placeholder images are also available on demand.

• Ready-made endpoints for products, users, posts and more
• Carts, recipes, quotes and todos sample data
• Placeholder image URLs on demand
• Custom response endpoint for your own JSON
• Auth endpoints for login testing
• DummyJSON Server package for local mock data

Frontend developers, mobile developers and QA testers who need realistic data for demos, prototypes and automated tests. It is useful for tutorials and workshops that should not depend on a live backend.

The site describes itself as a free API. Its data is fake and public, so do not send real personal data to it. The project is supported by sponsors and by donations, and the server code is available on GitHub. Plan for rate limits on heavy automated use, and cache responses in your own tests where possible.
